built at Rocky Flats, only some unspecified component parts. The plant will not give off “dangerous wastes” or use large quantities of water, gas, and electricity.When questioned further by reporters, AEC spokesman Dick Elliott states adamantly, “Atomic bombs will not be built at this plant.”
One small but devastating error escapes notice. The site criteria specifically state that the wind passing over the plant should not blow toward a major population center. But there is a mistake in the engineering report. Engineers base their analysis on wind patterns at Stapleton Airport, on the other side of Denver, where winds come from the south. Rocky Flats is well known for extreme weather conditions—rain, sleet, snow, and especially the prevailing winds, including chinooks that travel down the eastern slope of the Rockies from the west and northwest, directly over Rocky Flats and straight toward Arvada, Westminster, Broomfield, and Denver. Called “snow eaters,” chinook winds occur when the jet stream dips down and hits the fourteeners—the 14,000-foot mountains west of Denver—where they lose their moisture. The winds warm as they race down the lee side of the mountain range, and by the time they reach flat land, they’re hot and often exceed 100 miles perhour. Snow melts overnight. Sometimes chinooks snap telephone poles, blow out windshields, and overturn vehicles in the area around Rocky Flats.
One employee who notices the error is Jim Stone. An engineer hired to help design Rocky Flats before it opens, Stone is a careful and thorough man. Born during the Depression, he was sent to a Catholic orphanage when his parents couldn’t afford to raise him. His path to becoming an engineer has been hard won, and he brings years of experience to his job at Rocky Flats.He warns against the location of the plant “because Denver is downwind a few miles away.” He is ignored.
The name Rocky Flats is taken from the dry, rolling land dotted with sage and pine trees, a name chosen by early homesteaders who raised cattle and hay. Now it will no longer be ranchland. The money is in housing. Jefferson County and the entire Denver area are booming. Just over half a million in 1950, by 1969 the population of the Denver metro area has more than doubled. Jefferson and Boulder counties are two of the fastest-growing counties in the entire country. Thomas Mills, the mayor of Arvada, worries about housing. Rocky Flats plans to hire at least a thousand permanent workers immediately, and unlike in other nuclear towns, such as Los Alamos, workers will not be housed on-site. “The housing situation is rough here. We’ll receive the brunt of all that traffic to the plant because we’re on the only direct route to it,” Mills says. “The city is comprised mostly of small homes. There really is only one large apartment house.… It’s going to cause us lots of headaches.” By the first week of March 1951, extensive new home construction has begun.
The plant is surrounded by two tiers of barbed-wire fence stretching ten miles around the circumference of the core area. The first tier, three feet high, is to keep cattle out. The second tier, nine feet high, is electrified and patrolled by guards with guns, high-powered binoculars, and, eventually, tanks. With the exception of a two-story administration building, the plant’s buildings are built low to the ground, in ravines cut deep into the soil. The factory is almost completely invisible from the road. By early 1952, things are in full production. By 1957, nearly1,600 people work at Rocky Flats. Radioactive and toxic waste have to be dealt with from the beginning. Effluence is run through a regular sewage disposal plant and empties into nearby Woman Creek.Solid and liquid waste is packed into fifty-five-gallon drums. Much of what remains is incinerated.What spews from the smokestacks of the production buildings is expected to disperse by the time it reaches the outer limits of
